Mini is Britain's smallest puppy. Here's a photo of her next to a sheepdog. Mini is a three and a half week old puppy who opened her eyes for the first time this week. She was born in a litter of Chihuahua- Yorkshire terrier cross puppies. She weighed just 1.3 ounces (0.08 pounds) and was around the size of an egg. She's around a third of the size of other puppies and is expected to grow to only about 1.5 pounds when she is fully grown (her litter mates will likely be around 15 pounds).

Owner Emma Williams did not hold out much hope that the tiny pup would make it, given she had to wrestle her much larger siblings for milk from their mother. So Emma, who lives in Sandbanks, Dorset, decided to boost her growth by hand rearing Mini with formula milk and now the puppy is able to open her eyes and see the world for the first time.
